Detailed explanation-1: -The chemicals also attract white blood cells that “eat” microorganisms and dead or damaged cells. The process where these white blood cells surround, engulf, and destroy foreign substances is called phagocytosis, and the cells are collectively referred to as phagocytes.

Detailed explanation-2: -Phagocytic cells such as macrophages and neutrophils play an essential role in the defense of our body against invading microorganisms. Invading microorganisms are ingested by phagocytic cells and subsequently found in membrane-delimited phagosomes, where they are killed.

Detailed explanation-3: -Macrophages are effector cells of the innate immune system that phagocytose bacteria and secrete both pro-inflammatory and antimicrobial mediators. In addition, macrophages play an important role in eliminating diseased and damaged cells through their programmed cell death.
